Colin's WRX Car Audio System
�The main focus of work on the car has concentrated around the installation of the car audio system, which took about 3-4 months of working at nights and weekends on it in my shed at home. All of the work was carried out my myself, apart from the front kick panels which were constructed by Westend Sound. Many thanks must go to Ken & Stuart at Westend Sound for their assistance and technical input with the system.
My MY99 Subaru Impreza WRX.
The car remains basically standard apart from some minor cosmetic enhancements.
An Odyssey ES12V1000 battery replaces the standard item. O gauge cable runs through a 200amp fuse which is mounted on a laser cut stainless steel bracket, which also doubles as the battery tie down. All other power and ground cables have been upgraded, as well as the battery terminals to Stinger HPM items. A laser cut clear perspex panel covers and protects the battery and accessories.
The boot is home to the 3 amplifiers which power the system. Two Alpine MRV-1507 2 channel amps are mounted in white custom amp racks which are covered by vinyl clad trim panles. Perforated steel mesh inserts protect the amps while providing viewing of the amps and allowing heat to dissipate readily. The third amplifier, an Alpine MRV-F303 resides in the left hand side of the boot and is mounted rearwards behind a glass panel to allow viewing of the amps internals. A capacitor and a fused distribution block reside in the right hand side of the boot.

�Yet another killer logo from Boston Acoustics.
The right hand side of the boot houses a Stinger HPM 1 farad capacitor and a fused distribution block, behind glass panels.
The interior remains standard apart from the stereo upgrades. An Alpine CDA-7832R single CD receiver resides in the standard dash location. The remote control for the unit is mounted on a custom panel in the centre console, along with a switch for the auxilliary cooling fans in the amp racks.
Custom kick panels were fabricated from mdf and fibreglass and covered in vinyl. The kicks house a 4" midrange driver and tweeter from a Boston Pro 6.53 component set. Both speakers were axis mounted to aid in imaging and to provide a strong centre channel.
The 6" midbass driver from the 6.53 set is mounted on a custom mdf baffle in the standard speaker location. Generous amounts of Stinger Roadkill Pro and Dynamat Original were applied to both the inner and outer door skins, prior to a final application of Wurth spray on sound deadener. The result is a door that shuts like a Mercedes rather than a Subaru, and also provides a solid base for the speaker to deliver plenty of midbass.
The crossovers from the Boston set reside under the front seats, and are mounted on vinyl covered mdf panels. Stainless steel shields have also been fabricated and fitted to the front of the panels to protect the crossover from the rear passenger floor mounted heater ducts.
